How to use the Unitary Method Solver

The unitary method is a staple of the Pakistan class 5 mathematics syllabus: find the value of one unit first, then scale up. This unitary method calculator for class 5 solves these word problems in two visible steps — it shows the unit price and the final answer — so students can check their notebook working and learn the method, not just copy the answer.

  1. Enter the known total (e.g. Rs 240) in the Known total field.
  2. Enter the known quantity (e.g. 12 pens) in the Known quantity field.
  3. Enter the quantity the question asks about (e.g. 5 pens) in the New quantity field.
  4. Click Calculate — the tool shows the unit price and multiplies it out to your answer.

Formula

Unit value = Known total ÷ Known quantity. Answer = Unit value × New quantity. Example: 240 ÷ 12 = 20 per pen; 20 × 5 = Rs 100 for 5 pens.

Worked example

Question: if 12 notebooks cost Rs 240, what do 5 cost? Unit price = 240 ÷ 12 = Rs 20 per notebook. Answer = 20 × 5 = Rs 100. The student copies both steps into the notebook, showing the proper unitary method working.

Frequently asked questions

Find the value of one thing first, then multiply. If 12 pens cost Rs 240, one pen costs Rs 20, so 5 pens cost Rs 100. That two-step logic is the whole method.

No — this tool solves direct proportion only, which is what class 5 covers. Inverse proportion (workers and days) needs a different method taught in higher classes.

Yes. Use it for any direct-proportion word problem: distance and time, weight and price, or workers and output — just keep the units consistent.
